Product More Function Details 

Sports sunglasses could give an edge to athletes at all levels, including amateur "weekend warriors" who always are looking for ways to improve their performance in the sports they love.But in their rush to try the latest and greatest gear, such as new tennis racquets or shoes, many sports enthusiasts overlook a key factor in optimizing their sports performance-their vision. Excellent peripheral vision is produced from the curved,single-lens geometry.

The frame material we mainly choose(two types):

1.PC frame:

Pc as the name imples to polycarbonate, the feature is free wearing and comfortable, light weight, anti- 

shock, also flexible. but the price is more cheaper than Tr90 material. so it is widely used in the outdoor sport sunglasses field.

This material is more flexible than the PC material: softy, light weight,abrasion resistance,not easy to distort. but the price is much higher than the PC frame. 

these two material has its own advantages,but they also have common function:

-adjustable nose piece provide the perfect fit when you forget your wearing it.
